Heat Jaws is a fusion of Heatblast and Ripjaws from the show Ben 10. This fusion happens in the episode Dr. Animo and the Mutant Ray. I've trained this with about 25 screencaps from the episode in 1080p with no fan art included. Some things to note is that the AI likes to think the red arms and legs is armor. Teeth also might not generate well sometimes as well as the legs/feet not looking accurate, but everything else works good from my testing.
Positive Prompts: HeatJaws, furry, anthro, marine, amphibian, fire elemental, hybrid, green esca, light-grey sclera, no pupils, gills, light-green body, sharp teeth, big teeth, olive-green tongue, red arms, glowing hands, red legs, glowing feet, black shoulder pad, black waistwear
Alternate tongue color: dark-yellow tongue
If the hands appear magma red instead, then put "light-yellow hands" and it should resolve the issue.
